iMPRovEMENT IN LiQulo-cooLERs.

Specification forming part of Letters Patent No. 130,331, dated August 6, 1872.

To all whom t may concern:

Be it known that we, E. L. STROHEGKER and ALFRED IvnRsoN, Jr., of Macon, in the county of Bibb and State of Georgia, have lin vented a new and Improved Apparatus or Cooling Liquids and Making Ice 5 and we dohereby declare the following to be a full and exact description of the same,'reference being had to the accompanying drawing forming part of this specification, in which- Figure lis a sectional elevation of our invention, and Fig. 2 a side elevation of the interior can removed.

Similar letters of reference in the accompanying drawing denote the same parts.

This invention has for its object to provide for publie use a simple and convenient apparatus in which wines or other liquids may be expeditiously cooled or water frozen 5 and to this end it consists of a water-tight can, provided with curved radial anges on its outer surface, extending from top to bottom, and journaled within another can of such diameter that an annular space between the two cans will thereby be formed, which may be partially filled with any desired liquid, chemical, or compound, the curved llanges of the inner can acting, when the latter is revolved, to throw the liquid chemical upward, and cause a continuous circulation of the same around the revolving can, for the purpose of effectually subjecting the contents of the latter to its freezing properties, as will hereinafter more fully appear.

Arepresents a cylindrical-can or receptacle, provided with a removable cover, a, and B a smaller can, located within the receptacle A, and turning freely upon a pivot, b, attached to its bottom. The cover C ofthe can B is conical, and terminates in a mouth-piece or short tube,D, the upper end of which passes through a circular orice in the covera. The end of the tube D is made hexagonal, .or of other equivalent shape, constituting a seat for the correspondingly-shaped socket of the crank E. The cover O is provided with a bead around its lower edge, and its closely on the top of the can B. To hold the vcover in place hasps or catches F are employed, which are hinged to the can B, and have shoulders, which close over the bead of the cover C, as shown in Fig. 2. H H, &c.', represent radial anges on the periphery of the can B at suitable intervals apart, and extending from top to bottom of the same. These flanges are curved at their lower ends, as shown, and are sufficiently wide to extend nearly across the annular space B between the can B and the receptacle A.

1n operating our apparatus, we pour into the annular space B a suiiicient quantity of some suitable liquid chemical-such as, for example, nitrate of ammoniamixed with water-for the purpose of producing intense c'old around the inner can by evaporation or otherwise. If the article to be cooled is a liquid, it may be poured into the can B through the mouth D without removing the covers a C. The inner can being then revolved by its crank E, the flanges H agitate and stir the liquid chemicals in the space B', their curved lower portions throwing the same upward, creating a constant circulation7 and preventing any precipitation on the bottom of the receptacle A. By this means the liquid in the canB becomes thoroughly cooled in a very short time, and may then be poured out, as it was introduced, through the nozzle D. In making ice, the method of operation is the same, with some chan ge, perhaps, in the quantity of the chemical in the space B. A small quantity of water is placed in the can, and the latter is then -revolved sufficiently long to produce the desired quality of ice, which, after its formation, may be removed without breaking by simply detachin g the can from the receptacle A, loosening the catches E, and taking oli' the cover C. The liquid in the can B is prevented from being thrown through the tube D centrifugally during the operation by a cap, I, which is placed over the top of the same, as shown in Fig. 1, while the escape of any of the liquid in the annular space B is prevented by a collar, d, which projects from the tube D immediately under the oritice in the cover a.

This apparatus may be constructed of sheet metal, glass, stone-ware, or other suitable material, and constitutes a simple and convenient device for cooling or freezing liquids, its Y construction adapting it equally well for either purpose.

Having thus described our invention, what we claim is- 1. The revolving can B, provided with ra dial flanges H, curved at their lower ends, in

combination with the closed receptacle A, subcap I, arranged and operated substantially as stzmtally as described, for ythe purpose speciand for the purposes specified. ed.

2. The can B, provided with the conical cover C, secured by catches F, and the tube or Witnesses: mouth-piece D, the latter arrzmgedto receive the crank-arm E, end having the coller d and ED. L. srRoHEoKER. ALFRED IVEusoN, JR.
